Two Expensive Inventory Issues: Which Do You Fix First?Do you know the root causes of the four common inventory issues: out of stock, overstock, bumpy cash flow, and lost sales? Your goal is to have the right products in the right quantity at the right locations just in time to sell with terms from your supplier that allow you to use your money again before you pay the supplier. No one would argue the success of this strategy, so where is all the grief? In truth, there are four root causes to the most common inventory issues. Unfortunately, many companies fail to identify and act on these root causes, resulting in lost profits in the form of lost sales and higher operating costs.

  • Out of Stocks – Supply Chain Issues
  • Overstocks – Operation Problems
  • Bumpy Cash Flow – Planning & Finance
  • Lost Sales – Customer Service Issues

What Your Inventory Operation Isn’t Telling You

Our blog last week: Four Common Inventory Issues – Which Do You Want To Fix? addresses two of the four most common root causes to inventory issues, demand forecasting and lead time forecasting. The article also outlines how different inventory optimization actions can improve inventory performance. “Inventory optimization has been made to sound like the ’end all’ answer to these four profitability issues. Is it a state of nirvana for retailers that, if reached, magically removes all inventory issues? What is inventory optimization and is it truly the “final answer” to your inventory planning and operation execution issues?”*

There are four steps you need to take in reviewing your inventory operations. Last week we discussed steps 1 and 2 and outlined some methods for you to use to measure your opportunity. This week we wrap up with the remaining two steps for you to review. These final two create more issues than the first two because you can have a perfect demand forecast and lead time – but if these two steps are not addressed the cost to profits will be substantial.

Lead Time Forecasting - What's New

Order Cycle and Optimization

Step 3: Inventory Order Cycle Optimization is needed to determine the most efficient quantities of product to buy. Real inventory optimization around an optimum order cycle is pull methodology, from the bottom, a pull based on individual product/location service goals. This is the best way for your business to be customer centric as it lowers your inventory costs and raises your sales and service level attained. The pain of reordering based on service is that it follows the market and not a plan or open to buy. While a system that calculates reorder cycle based on service levels is very responsive to the customer and results in less inventory, the danger for some is that replenishment seems a higher priority than plan.
Order cycle optimization decisions are best made when future needs, the demand forecast and your company’s cost structure, product acquisition and carrying costs, are integrated into the equation. The resulting optimum economic buy quantities provides the best possible cash flow and increases customer sales.
Many companies and many legacy software applications are based on plan. Often companies set their reorder cycle (supplier order schedule) based on a weekly or monthly schedule. This is not responsive to the marketplace today and results in overstocks, out of stocks and cash flows that are weighted heavily in the first week of any month – multiple inventory expenses just from how you schedule orders!

Visible Supply Chains Then and Now

Step 4: Inventory optimization needs supply chain visibility tools that can monitor demand and supply, while providing configuration by individual users and management. Monitoring requires effective exception management that is, again, configurable by users based on product/ location hierarchies and multiple management levels. The uniqueness of your internal and external business workflow activities and goals should be defined in your configurable exception management tools and process which dynamically change by recognizing market changes over time. A flexible tool allows you to create new reports and screens that support resolving new exceptions, providing the best possible results.
